    • Product overview

      In Abcam's Granzyme B Inhibitor Screening Assay Kit, active human Granzyme B enzyme hydrolyzes the specific substrate to release the quench of fluorescent group, which can be detected fluorometrically at Ex/Em = 380/500 nm. In the presence of potent Granzyme B Inhibitor, the hydrolyzation of substrate will be impeded. The Kit provides a rapid, simple, sensitive and reliable test suitable for high throughput screening of Granzyme B inhibitors or characterize/study Granzyme B inhibitors. Inhibitor control, Ac-IEPD-CHO is included to compare the efficacy of test inhibitors.

    • Notes

      This product is manufactured by BioVision, an Abcam company and was previously called K169 Granzyme B Inhibitor Screening Kit (Fluorometric). K169-100 is the same size as the 100 test size of ab157405.

      Granzyme B (GZMB, EC number 3.4.21.79) also known as Granzyme-2 is a serine protease stored in the granules of activated cytotoxic T cells and NK cells. Upon target cell contact, Granzyme B is directionally exocytosed and with the assistance of perforin enters the target cell. With its unique substrate specificity (Granzyme B prefers an aspartic acid residue at the P1 site of its substrates), Granzyme B processes and activates various pro-caspases thereby inducing apoptosis in the target cell.

      The standard is affinity purified.

    • Function

      This enzyme is necessary for target cell lysis in cell-mediated immune responses. It cleaves after Asp. Seems to be linked to an activation cascade of caspases (aspartate-specific cysteine proteases) responsible for apoptosis execution. Cleaves caspase-3, -7, -9 and 10 to give rise to active enzymes mediating apoptosis.
    • Sequence similarities

      Belongs to the peptidase S1 family. Granzyme subfamily.
      Contains 1 peptidase S1 domain.
    • Cellular localization

      Cytoplasmic granule. Cytoplasmic granules of cytolytic T-lymphocytes and natural killer cells.
